Adiprene® Green, a new renewable solution for PU elastomers

LANXESS has developed a new range of MDI polyether prepolymers containing renewable raw materials. Adiprene® Green products are suitable as replacement for existing fossil based polyether prepolymers to manufacture highly durable polyurethane (PU) elastomers.

Adiprene® Green was developed to create a range of renewable raw material-based prepolymers which allow the PU processor to produce components with a reduced CO2 footprint.

  • The share of renewable raw materials varies between 30 to 90 % dependening on the targeted system hardness.
  • Up to 30% CO2 reduction compared to fossil-based prepolymers due to the use of polyether polyols based on starch (depending on the system).
  • Up to 27% energy savings
  • Existing PU processing capabilities remain applicable
  • The properties of the final polyurethane elastomer are similar to established elastomers based on fossil based polyether or even better.

 

Adiprene® Green prepolymers are easy to handle

Adiprene® Green prepolymers are processed in an identical manner to conventional prepolymers. No modifications to material handling, process temperatures or mixing ratios are necessary. In addition, the reactivity profile and demolding times are similar to fossil based polyether prepolymers.

When reacted with 1,4 butanediol, a range of PU elastomers with a hardness from 40 Shore A to 60 Shore D can be achieved. As the PU system is versatile, Adiprene® Green can be hand-mixed or machine mixed. Moreover, the prepolymers can be processed with Vibracat® catalysts from LANXESS. Products of the Adiprene® Green line are well suited for demanding applications such as roll covers, wheels, press sleeves or non-pneumatic tires.

 

Product portfolio

The Adiprene® Green product line includes MDI Ether based prepolymers with a wide range of hardnesses that can be processed as 2K or 3K. The line allows to reach broad hardness range while maintaining excellent properties.
